PAPER BOX.

Specification of Eetters Patent.

Patented Feb. 14, 1922.

Application filed December 2, 1918. Serial No. 264,912.

To all whomit may concern:

Be it known that I, FRANK J. lVinsiuAN, a citizen of the United States,and a resident of Monroe, Michigan, have invented a certain new anduseful Improvement in Paper Boxes, of which the following is aspecification.

This invention relates to paper boxes for holding tobacco or othersimilar commodities.

One object of the invention is to provide novel and improved means forclosing the bottom of the box.

Anotherobject is to provide novel and improved means for closing the topof the box.

It is also an object to provide certain details of construction tendingto increase the general efficiency and the desirability of a box of thisparticular character.

To these and other useful ends the invention consists in mattershereinafter set forth. and claimed.

In the accompanying drawings Fig. 1 is a perspective of a be}: embodying the principles of the invention, showing the top and bottom open.

Fig. 2 is a similar view showing the top and bottom closed.

Fig. 8 is a vertical section on line 33 in Fig. 2.

Fig. 1 is a vertical section on line iin Fig. 3.

Fig. 5 1s a horizontal section on line 55 in Fig. 4:.

Fig. 6 is a plan of the blank from which the box is made. i

As thus illustrated, the blank comprises the rectangular side wallsections 1, 2, 3, 1, and 5, with a flap 6 for connecting the two ends ofthe blank together. The section 1 is provided at its upper edge with aflap 7 having a tongue 8, and the lower edge of this section is providedwith a flap 9 having a flexible tongue 10, the latter being preferablyscored one or more times at 11, thereby to make the tongue flexible. Theupper and lower edges of the sections 3 and 5 are provided with shortflaps 12 and 13, which are substantially rectangular, and whichcooperate with said other flaps to form the closures for the top andbottom of the box, as will hereinafter more fully appear, The

section 1 has half-moon-shaped opening 14 therein, and a small flap 15at its lower edge.

ln making the box, the section 1 is folded over upon the section 2, andthe edge 16 of the section 1 is secured in place by glue or otherwise,so that awall of double thickness is provided. Then the blank is foldedto bring the strip or flap 6 inside of said double wall, and is glued orotherwise secured thereto, whereby a rectangular box is provided havingrelatively wide front and back walls formed by the sections 1, 2, and4-, and relatively narrow side walls formed by the sections 3 and 5, asshown in Fig. 1. Thereafter, the tongue 10 is bent or flexed upward andthen inserted upward between the lower edges of the sections 1 and 2,the flap 15 facilitating this insertion by preventing the tongue 10 frombeing inserted inside of the box, instead of between the twothicknesses. The tongue 10 having been flexed stated, it tends to springinto the opening 1 1 as soon as it is inserted fair enough between thetwo thicknesses of the double wall. In this way the flap 9 is heldagainst the bottom of the flaps 13 and 15, thereby tightly closing thebottom or lower end of the box. When the contents, such as tobacco,enters the box, the weight thereof will press the tongue 10 downward(see Fig. 3), thus folding it across the lower edge 17 of the opening14:, and forming a sort of lock to keep the bottom flaps closed.

The top of the box is closed by folding down the flaps 12, and by theninserting the tongue 8 downwardly between the sections 1 and 2, theouter thickness 2 being cut away or formed with a broad shallow notch at18 to facilitate this insertion. In other words, the tongue 8 is bentdownward against the outer surface of the upper edge portion of thethickness 1, and then slides downward inside of the thickness 2, muchmore easily than would bethe case if both thicknesses where of the sameheight or were flush at their upper edges.

It will be seen that the box shown and described can be partiallyfolded, leaving the top and bottom open, and then shipped in a flattenedor crushed condition, thus avoiding waste space in shipment. The tobaccomanufacturer or other user will then Close the bottoms of the boxes andafter they are filled the tops will then be closed in. the mannerdescribed.

The two thicknesses 1. and 2 hold the flap 8 between them, by thepressure exerted thereon, so that the box is held closed at the top.These two walls 1 and 2 also tightly clamp the tongue 10, the latterhaving a portion which is aswide as the flap 9, whereby displace ment ofthe latter ismore ell ectually prevented. The tongue 10 when folded, asshown in Fig. 8, forms a lock to very effectively hold the bottom of thebox closed. When the contents of the box is poured out or removed, thetongue 10 can then be lifted, and the flap 9 and tongue 10 then bepulled downward to open the box, if such is necessary. The entire box,however, is formed from a single blank made of paper or other sheetmaterial.

What I claim as my invention is 1. In a box, a double wall having anopening in the inner thickness thereof, so that said opening is covered,and a bottom flap having a flexible tongue adapted for insertion betweenthe two thicknesses and through said covered opening into position to bedepressed by the contents of the box.

2. A box as specified in claim 1, said opening having a straight loweredge, and a curved upper edge and said tongue being adapted to engagesaid edge to lock the flap in position.

3. A box as specified in claim 1, said tongue being creased transverselyand there- 'by adapted to bend inward to enter said opening, and thendownward upon the lower edge of said opening.

4:. A box as specified in claim 1, said inner thickness having a flapbelow said opening 1 ,aoavm to guide and facilitate the insertion of thetongue, which flap rests on the bottom of the box.

5. A structure as specified in .claim 1, said box being formed in itsentirety from. a single blank having said opening and tongue.

.6. In a box made from a blank, the combination of side walls which areadjacent each other in the blank, a bottom wall, and a loldable flaphaving a flexible portion for insertion between the side walls forattachment to the inner side wall to hold the bottom wall in place,having folded interlocking means to prevent withdrawal of the flap.

7. A structure as specified in claim 6, said interlocking meansinvolving provisions whereby said flap is folded and held against theinner surface of the inner side wall by the contents after the box isfilled.

8. A structure as specified in claim 6, in combination with a provisionto guide and facilitate the insertion of the flap, said provisionbeingin the form of a flap which becomes a part of the bottom when the box isformed.

9. A box blank comprising the vertical side walls for the box (1, 2, 3,4, 5 and 6) the bottom wall of the box (9), flaps (18) for said bottomof the box, an opening (1.4) in one (1) of said vertical walls of thebox, and a flexible flap (10) forming part of said bottom wall andadapted for insertion between two 01' said vertical Walls (1 and 2) andthrough said opening into the box, all connected and arranged so thatsaid two vertical walls (1 and 2) are adjacent to each other in theblank, substantially asshown and described.
